The next issue will occur during “make install” (again on CentOS 7). The syntax for adduser is incompatible, instead of:
adduser urbackup --system --quiet --group …
it should be:
adduser urbackup --system --user-group
CentOS/RHEL version of adduser doesn’t understand flags “–quiet” and “–group”. “–quiet” can be removed, but “–group” should be changed to “–user-group”.

ERROR: Fatal error during backup. Backup not completed

This is a new server install (not upgrade) of a UrBackup server >= 2.0.5 (tree hashing) and the client uses “block differences - hashed” transfer mode?
Then I ran incremental backup:

ERROR: Fatal error during backup. Backup not completed
ERROR: FATAL: Backup failed because of disk problems
If it is changing during the backup (mysql running?) that would be expected outcome. It is currently hashing twice using different methods and comparing the result. If no problems crop up, I’ll remove that with the next version.
There is a work-around for --paths not working in the remove script but not in the create script. Will be fixed.
